Hi this thesis, the technique of detector array is used to obtain the location of anomalous infrasound, it is the basic of the study of prediction of earthquake. to derive useful information by using spectrum analysis on infrasonic signal. then combing with other methods a forecast could be made
本課題主要是利用數字技術,採用用傳感器陣列計算異常次聲波波源的方位,這是今後預測震中位置研究的前提;並對次聲信號進行頻譜分析,提取有用的關于臨震次聲方面的信息,再結合其他的預報方法,作出準確的地震預報。In order to calculate synthetic seismograms in a layered half - space with the sources and the receivers at close or same depths, an efficient numerical integration method - the peak - trough averaging method ( ptam ) is proposed, based on the repeated averaging method
摘要為了計算在震源和接收點深度相同或相近情況下分層半空間介質中的合成地震圖,在重復平均法的基礎上加以改進,提出一種有效的數值積分方法峰谷平均法。The differences between this method and other similar methods are : ( 1 ) the fast synthetic source record algorithm based on the wave theory is adopted in prestack depth migration. ( 2 ) the plane wave source is used in migration that is consistent with the velocity analysis method. ( 3 ) by using the controlled illumination, the distortion of the plane wave source wavefield due to the lateral velocity variation is avoided therefore the error of velocity analysis is reduced and ( 4 ) the practical velocity spectrum makes the interactive migration velocity analysis feasible and convenient
與其他類似偏移速度分析方法的不同點在於: ( 1 )疊前深度偏移採用基於波動理論的快速合成震源記錄演算法; ( 2 )偏移方法採用平面波震源,與速度分析方法一致; ( 3 )應用控制照明技術,避免了因橫向變速而導致的平面波震源波場在傳播過程中的畸變,從而減小了速度分析的誤差; ( 4 )實用的速度譜設計,使交互偏移速度分析可行且易於操作。On the basis of gap ' s temporal - spatial characteristics in and around source area before an earthquake, we propose a method to estimate characteristic parameters ( characteristic distance and time ) in the region - time - length ( rtl ) algorithm and introduce the method of correlation coefficient developed by some authors in 2006 to determine the characteristic parameters
摘要根據地震前震源及周圍地區出現的空區的時空特徵,提出了一種估計「區域時間長度」演算法中特徵參數(特徵距離和特徵時間)的方法,並介紹了2006年一些學者提出的用相關系數估計特徵參數的方法。分享友人
